At some point, there was water on Mars. We have known this to a high level of certainty since at least 2004, when the Opportunity rover discovered Martian spherules, also known as “blueberries” for their round shape and blue hue in false-color images. These small mineral deposits of hematite could only have formed in liquid water.In 2015, planetary scientists surmised that significant deposits of liquid water exist on Mars today, lurking just below the red surface....

For the first time, a major metropolitan transportation system in America is getting a level of security comparable to an airport. The Los Angeles subway system will be installing body scanners which will screen passengers for weapons and explosives.The security will look different than it does at an airport: Passengers will walk through halls like they have before, only this time they will be walking through Thruvision TAC-TS4 portable terahertz millimeter wave passenger screening devices....

Wow Air flew on a purple plane and a promise too good to be true. The no-frills airline debuted in 2011 with rock-bottom prices on transatlantic flights, some as low as $99. With it came the dream of low-cost, long-haul air travel to the masses.The world just woke up from the dream. Yesterday morning, Wow Air abruptly disbanded its entire operation after eight years, and the result was total chaos. Pulling the plug on an entire airline with no advance notice left upwards of 2,700 passengers stranded on both sides of the Atlantic, left in the lurch without a tangible promise of refunds or a way to get home....

Flashback to 2008. iOS 2.0.1 just brought some sort of “app store” to the new iPhone 3G. Rumors are swirling about a new Microsoft operating system codenamed “Windows 7.” And in September, Google releases the first version of its new Chrome browser.In the seven years since, we’ve seen our fair share of iterations, reboots, and sequels but no new web browsers. Until now.Today, Windows 10 launches, and with it, the new Windows 10-exclusive Microsoft Edge Browser....

The coronavirus—which causes a disease that’s been named COVID-19—has reached a global death toll of more than 180,000 people and infected more than 2.6 million all over the world.COVID-19 has now reached all 50 states and every continent except Antarctica.There are some simple precautions the general public can take include social distancing—even if you yourself are in good health and not generally worried about contracting COVID-19—thoroughly washing hands with soap and water for at least 20 seconds, using alcohol-based sanitizers, and avoiding touching your face....

When I’m in charge of a car company, we’re going to have one strict rule about interior design: Make it so it doesn’t cause you to crash the car. You’d think this would already be in effect everywhere, but no. Ever since the arrival of the iPhone, car designers have aspired to replicate that sleek, glassy aesthetic within the cabin. And it never works, because you tend to look at a phone while you use it....

Do most cocktails produce a chemical reaction, or do the ingredients simply taste good together?Cocktails can indeed produce chemical reactions, but those most often occur in your liver, or perhaps between you and your drinking companion (wink, wink)—not in a high-ball glass. When most of us think of chemical reactions, we picture something like baking soda and vinegar. Something impressive, volcanic. The reactions that occur in cocktails are more subtle—so subtle, in fact, that many scientists wouldn’t even consider them true chemical reactions, but rather “material changes....

The U.S. Justice Department has filed charges against four members of China’s military on suspicion of perpetrating the March 2017 Equifax data breach.About 145 million Americans were impacted by the breach, which leaked highly sensitive information about consumers, including their Social Security numbers.The FBI is looking for tips on the four men in question.Just shy of three years since the infamous Equifax data breach leaked sensitive personal information about nearly half of the U....

Scientists have found evidence of a new exoplanet candidate orbiting our closest stellar neighbor, Proxima Centauri. This exoplanet candidate, Proxima c, likely has a mass six times that of Earth.But it’s unlikely that life would survive on the planet, given its frigid temperatures.The red dwarf star Proxima Centauri is our closest stellar neighbor; the star system is a measly 4.2 light years from Earth and can be seen with the naked eye....

Since I’m one of the few guys on TV who own old cars and enjoy restoring them, people often contact me about their car projects. Some are restorations that folks may have barely started. Others are vehicles they’ve labored over, but never quite finished. Then there are the cars that people have owned for 40 years, and now they ask me if I’d like to buy them so they end up in a good home....

Diving headfirst onto a trampoline covered in almost a thousand mousetraps might not seem like a good idea. Filming it in super slow motion, however, definitely is.That’s exactly what the Slow Mo Guys decided to do. Dan volunteered to jump onto the trampoline full of mousetraps for science or something, and Gavin records the event for posterity. Fortunately, Dan makes it through the ordeal with nothing but a hair injury, and Gavin captures an incredible scene as a thousand mousetraps go off all at once....

A Brooklyn startup called Launcher has made its rocket engine’s entire combustion chamber in one 3D print.Launcher received $1.5m in Air Force funding during a call for launch technology—the Air Force is considering rockets as a way to transport cargo on Earth.Large 3D printers are costly, but Launcher claims this single piece technology still reduces their cost.A rocket startup called Launcher has made the largest liquid-fuel combustion chamber ever 3D printed in a single piece, requiring a custom-made 3D printing setup....

Media Platforms Design TeamYesterday our local Mercedes-Benz rep tossed me the keys to a $452,000, 617-hp Mercedes-Benz SLR and told me only to have it back before sundown. Um, okay, if you insist.Dutifully, we report the following discoveries:Surprisingly, you notice the brakes first. The pedal is very stiff and the brakes are very potent. Around town you need to concentrate on braking smoothly. And they’re ceramic discs so they squeal until they’re warm....

Could the key to nuclear fusion be a low-temperature reactor with no radioactive fuel or waste?Startup HB11 joins other groups seeking to shift our nuclear paradigm altogether. In HB11s reactor, lasers collide hydrogen and boron together to generate charged helium atoms.Scientists in Australia are making some astonishing claims about a new nuclear reactor technology. Startup HB11, which spun out of the University of New South Wales, has applied for and received patents in the U....

Media Platforms Design TeamWhen President Barack Obama made his dramatic Sunday night announcement that U.S. forces had located and killed Osama bin Laden inside Pakistan, one of the first questions many asked was: How could U.S. officials be so sure it was really bin Laden? The answer came quickly. While the body was identified through photos and by bin Laden’s wife, it was also the seemingly incontrovertible proof of DNA that gave officials such ironclad confidence in the dead man’s identity....

Some species of ants can exhibit some strange behaviors, from using their jaws to launch themselves great distances to building bridges and rafts with their own bodies. But none compare to the strange Colobopsis species of southeast Asia, whose members can self-destruct to attack predators.The first species of exploding ants were discovered in the early 20th century, but since 1935, no new species have been discovered. A group of researchers decided to embark on an expedition to find more examples of this strange type of ant....

A pair of MIT researchers discovered a way to construct an artificial intelligence that’s only about a tenth the size, without losing any computational ability. The breakthrough could allow other researchers to build AI that are smaller, faster, and just as smart as those that exist today.When people talk about artificial intelligence, they’re mostly referring to a class of computer programs called artificial neural networks. These programs are designed to mimic how our own brains operate, making them very intelligent and creative....

Senator Ed Markey of Massachusetts has announced on Twitter that the Senate will officially introduce a resolution to overrule the FCC and reinstate net neutrality regulations. The resolution, made possible by the Congressional Review Act, would allow Congress to both reverse the FCC’s decision and also prohibit the FCC from making any similar decision in the future. Supporters are, for the moment, one vote shy of a majority in the Senate....

Advancements in 3D printing have made it possible to print everything from an aerodynamic smart car to a full-blown house. But Stratasys, the largest producer of 3D printers, has announced a more practical first for the industry: a 3D printer that can print in multiple colors and materials in a single build.Jonathan L. Cobb, executive vice president of marketing, revealed the Stratasys Objet500 Connex3 during a press event on Sunday at SolidWorks 2014....

The U.S. Army is developing a super long range gun. How long? Try over 1,000 miles.The Strategic Long Range Cannon (SLRC) resembles the 20th century guns used to bombard battlefields from miles away.The new gun will likely be used to destroy enemy defenses from long range, opening the door for friendly ships and planes.Leaked images of the U.S. Army’s new super gun have emerged on social media, showing for the first time the mysterious new weapon with a claimed range of over 1,000 miles....
